We use a LUA script for Eavesdrop and never had this issue.

Looking at the FS documentation, you can use ​w1@ext to speak with the callee or w2@ext to speak with the caller.

Here are the DTMF signals during eavesdrop

2 to speak with the uuid

1 to speak with the other half

3 to engage a three way

0 to restore eavesdrop.

* to next channel.

Is it possible you pressed any DTMF key during the call? If not, you could perhaps you could try w0@ext ?

Subject: [Freeswitch-users] eavesdrop

 

I need to enable client to eavesdrop on certain calls. The fs is in a penitentiary institute and certain types of criminals (i..e mafia related) must be listened.

 

I am trying to implement eavesdropping like so:

 

api originate {sip_secure_media=true}user/$ext &eavesdrop($uid)

 

(where, I hope, $ext and $uid are self-explicatory)

Is there ANY way to mute the microphone of the eavesdropper? It’s a bit of a give-away if the criminal can hear the background noise

 

Thanks

 

Francesco
